@JoKing do you have any particularly good perl 6 references?

Jo King

@primo github.com/AlexDaniel/6lang-golf-cheatsheet is good for char golfing tips

Other than that, it's good to have the Operator page up for reference

primo

thanks for the link, the first tip alone just blew my mind

although i suppose it's only useful in an "any char counts as one" context

It usually doesn't save bytes, except for fractions or larger numbers like 𖭡 (1000000000000)

@dylnan Random idea: Because that challenge requires as many unique bytes as possible, try converting it to a Jelly -u program. (take input as UTF8) That way there are more bytes (so probably more unique bytes) and because Jelly is very error-resistant I think it should work.

Last time you had a problem with "prime factorization in polynomial time" right...

> So if the modularity theorem were found to be true, then by definition no solution contradicting Fermat's Last Theorem could exist, which would therefore have to be true as well.

Random quote from Wikipedia.

People could prove that a conjecture implies another conjecture, while both were unsolved at that time.

Leaky Nun

right, there are lots of conjecture on transcendental number theory

Schanuel conjectures implies that e and pi are algebraically independent over Q, that e^e is transcendental, etc

Fatalize

@LeakyNun Assuming that we know that 3 is prime?

Leaky Nun

you don't need that

user202729

What can be assumed?

Assume that we don't know the definition of a prime number?

Leaky Nun

12:34

well you can assume 3 is prime if you want

Fatalize

Well it needs to be the sum of 2 primes, and 7+1 doesn't work cause 1 ain't prime, 6+2 doesn't cause 6 is even, 4+4 doesn't because 4 is even, so it has to be 5+3 and so 5 is prime

Leaky Nun

bingo

Fatalize

(and 3 is prime too)

But I highly doubt we'll get a proof of the goldbach conjecture that doesn't make use of other theorems that themselves prove that 5 is prime :p

ngn

@LeakyNun just-as-valid a CMC: show that the negation of the goldbach conjecture implies that 5 is prime

Leaky Nun

do you have an answer though

ngn

12:38

@LeakyNun me?

Leaky Nun

yes

Fatalize

5 is only divisible by 1 and itself so it's prime, knowing some numbers greater than 3 cannot be written as the sum of 2 primes :p

ngn

of course :) try dividing 5 by 2 3 4

statements of the kind "if false then x" and "if x then true" are trivial

so, the truth value of "5 is prime" is independent of the goldbach conjecture :)

Leaky Nun

23 mins ago, by Leaky Nun

where's the fun in that

Cat Wizard

13:31

@LeakyNun Let us take 12. Via the Goldbach theorem, twelve is the sum of two primes. If we subtract 2 we get 10 which is not prime, because it is divisible by 5. If we subtract 3 we get 9 which is divisible by 3. 6 gives us 6 which is divisible by 2. Thus 5 and 7 must be prime because they are the only pair left that add to 12.

Now I'm wondering if we could define primes by the goldbach conjecture. ...

Leaky Nun

lol

Cat Wizard

For example if you say Every even integer greater than 2 can be written as the sum of to xs. You can already show that 2 must be an x.

Oh wait no.

I forgot 1 was a number

Erik the Outgolfer

wait isn't 1 a number anymore o_o

Cat Wizard

The ancient greeks didn't believe 1 was a number.

That's why it isn't prime.

Fatalize

That's not the reason why 1 isn't prime

Zacharý

13:43

There's a reason one isn't prime ... something to do with unique prime decomposition...

Fatalize

1 isn't prime because it's convenient for many theorems and definitions that it's not

Cat Wizard

@Fatalize Those theorems were made after the fact using the fact that 1 wasn't prime in the first place.

Now were just stuck with this tradition cause that's how the greeks did it.

Fatalize

That's incorrect

Zacharý

^

Fatalize

Many mathematicians considered 1 to be prime even relatively recently (19th century)

Cat Wizard

13:49

It's not necessarily a bad thing. I mean it's pretty arbitary what numbers end up being prime, someone had to make the descision as to whether 1 was prime eventually, could have gone either way.

Now 2, is a different story. whether 2 is prime still contentious to this day.

Fatalize

Why would that be contentious?

Cat Wizard

Because 2 is even.

mınxomaτ

EP voted against link tax and upload filters today \o/

Fatalize

@CatWizard How is that a problem?

Cat Wizard

Well the prevailing standard has been not to let even numbers be prime. 2 kindof got grandfathered in (ancient greeks once again), despite this fact. A lot of the more modern theorems use only odd primes, to avoid the problems with 2.

Fatalize

13:54

The fact that even numbers are not prime except is precisely a consequence of 2 being prime, so that makes no sense

Cat Wizard

If I made the definition of prime I'd probably include 1 (and maybe 9), leave out 2. Makes things a lot cleaner.

Fatalize

especially considering that the fundamental theorem of arithmetic doesn't work if 2 isn't prime

@CatWizard …9?

Zacharý

Hey, xcoder changed his logo!

He's trolling you

Cat Wizard

There are arguments to be had on each side, that's why it's so contentious.

@wastl I assume it's Turing-complete, but haven't tried to prove it yet ... Simple: l executes one step of Conway's Game of Life ∧ GoL is TC ∴ 2DFuck is TC ∎

wastl

14:51

@Adám How could I miss that????

Cat Wizard

@Adám It's not quite that simple. It needs to be able to repeatedly execute steps of GOL and halt conditionally.

wastl

@CatWizard What kind of halting conditions would be necessary for that? Just a simple "is this cell dead/alive"? Or something more complex?

Cat Wizard

I don't remember what the halting condition for GOL is, but I think it is something like, if the state is not different from the last, or something similar.

Erik the Outgolfer

that's what I've seen as the halting condition most of the time, which I consider plain wrong

it should be "if the state is the same as a previous one"

Cat Wizard

GOL is not a very good way to prove something is TC.

user202729

@CatWizard I think α is 1.

Cat Wizard

Prime number

A prime number (or a prime) is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 6 is composite because it is the product of two numbers (2 × 3) that are both smaller than 6. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product...

5. Push to origin

(It's kinda hacky but it works)

i think I've seen maybe two people in existence who do native 4K

and they have really high end shit

FreezePhoenix

@quartata and 4K is what precisely?

Pavel

2160p

@quartata I agree you don't need 4k but 1080p is this day and age is just "normal quality".

quartata

1080p60fps is an important distinction in terms of storage capacity

I can't handle 1080p60fps video personally

At least not in long durations

FreezePhoenix

Guys... just use the XZ archive

DJMcMayhem

I'd consider 1080p high quality. It's not exceptionally high-quality, but it's still high-quality

FreezePhoenix

21:12

it's a random access memory archive format

quartata

(I have to render my demos in 720p60fps, cause it's all uncompressed)

Downgoat

@quartata 1080p is not 'low quality' but it's definitely not high quality. Not to mention google photos will probably re-encode the crap out of the uploaded videos

Pavel

@quartata I think I'd rather see 1080p30fps than 720p60fps

Downgoat

60fps is great and all but powerpoints and presentation recordings do not need it

FreezePhoenix

Honestly the next universal video format will be an extension of MP4 and XZ and EXE that simply is an inline XZ file unpacked using a builtin extractor and feeds the file explorer the result video #SoEasyAndTheDevsHateIt

quartata

21:16

@Pavel on gameplay?

Downgoat

demo = gameplay?

FreezePhoenix

@Pavel Same.

Pavel

@quartata Yeah. If I'm playing, I'd want 60fps, but if I'm watching, I want a higher resolution.

quartata

I should do the math on 1080p30fps

I think it's 2 GB/s

FreezePhoenix

@quartata That's... silly.

Erik the Outgolfer

21:19

@quartata uh, really?

quartata

still, point stands

Downgoat

@quartata 222MiB/s

quartata

Yeah checks out

1920*1080*3*30

Got it off by an order of magnitude

Still a nuisance but not too bad

Ah I remember where I got 2 GB/s

If I want to render at a higher frame rate for motion blur

Pavel

Why would you want motion blur

quartata

~1 GB/s at host_framerate 180

Anush

21:29

hi all

quartata

@Pavel because it's cool and Freeman's mind does it

FreezePhoenix

@quartata that's without any compression at all. Most video formats use high compression.

quartata

I know.

Can't here

Valve's h264 looks like hell frozen over

complete loss of colors

There are programs that use named pipes to keep the frames in memory one at a time but it's so slow

Pavel

What's h264

quartata

MP4

Anush

21:37

another attempt at a fastest-algorithm question in sandbox

Downgoat

@quartata wait what

A: Sandbox for Proposed Challenges

How quickly can you match two sets? Consider two sorted arrays of integers X and Y of size \$\lfloor \sqrt{n} \rfloor\$ and n respectively. I define a matching to be a set of pairs with one integer from X and one from Y in each pair. A matching must have exactly \$\lfloor \sqrt{n} \rfloor\$ pai...

quartata

Actually the one I used to use I think uses FUSE

just whatever to intercept the writing of the tga files

Q: Creating an If-Statement from Scratch

An if-statement is typically a built-in construct in languages. However, I am wondering if there is a way to construct an if-statement from some other primitives. I am also wondering how to do this with Boolean algebra, and there is a link there to how to represent if/else statements with circuit...

Quine Relay! answer-chaining quine A quine relay of order \$n\$ is a series of programs \$P_1\dots P_n\$ in distinct languages such that each program \$P_i\$ outputs \$P_{i+1}\$ and \$P_n\$ outputs \$P_1\$. For example, a 2-quine relay can be seen here: Ruby → Perl 6: This Ruby program: $><<...

"post your questions in sandbox, people"

Erik the Outgolfer

happens a lot

FreezePhoenix

22:46

@LeakyNun Uh... Was I supposed to?

Leaky Nun

you're supposed to post it before you post it to main

but the guy way above me seems to not have noticed that

Zacharý

Actually, it was deleted then reposted to Sandbox, I think

Erik the Outgolfer

@LeakyNun well, that's how it should be, but people sometimes do the goof over main (first post), get a reference to the sandbox in the comments, and then decide to delete and post in the sandbox

Leaky Nun

ok

Erik the Outgolfer

and, if the main question has accumulated downvotes, they often decide to post the fixed version (if any) as a new one

that's, imho, simply shameless duplication of own deleted content due to former bad reviews, just live with it and move on

for the editing, you can very well do the edits in the Ask Question page, but not post a new question, and instead undelete and immediately apply the edit
